你太抬举我了，我大一时学的C啊，好久都没搞了，现在改用delphi了。
这么晚了还不睡啊，我看看吧，不打包票。

linuxcici · 2005-07-10

非常谢谢你了,我下学期要用C参加学校比赛,关键就难在这里了.

ak_2005 · 2005-07-10

to linuxcici:
不知道你在什么系统下运行的?
第一个程序可能与系统权限有关系,我是在XP下运行的,编译没问题,运行提示Abnormal Program Termination.一行都不执行.你可以装个98试试, 把运行结果告诉我.因为98的DOS才是纯DOS,2000以上只是一个假的命令系统,所有操作都会受系统控制,特别对于硬件的操作,每一项都有权限的(典型的比如关机 ).
关于第二个,这个程序没用系统定时,当然不能同步播放,一定要用定时器(可以参照第一个程序).

linuxcici · 2005-07-10

喔.我用的也是window XP第二版系统,也是运行提示Abnormal Program Termination.

至于windows98我还要去试一试,请问那第一个有中断的程序按道理可以有效果的吗？
我在学校机房的window 2000 试过都不行啊.

我试过可以在windowx xp运行.这段代码只是播音乐,只能是单声道的.但是如果把一首mp3转换成wav就播放不了.

总结:我们的老师说可能是声卡的兼容问题,你说呢?

ak_2005 · 2005-07-10

第二个程序没用中断,当然可以了。我认为不是声卡的兼容问题，是音乐的格式问题。
WAV格式是“原汁原味”的，没经过压缩的，而MP3是经过压缩处理过的。

ak_2005 · 2005-07-10

>>请问那第一个有中断的程序按道理可以有效果的吗？
再次看了第一个程序，有问题，mian函数里面一句也不回执行（你可以设断点，再单步跟踪），到底是什么原因呢？

linuxcici · 2005-07-11

大哥我不懂怎么单步调试啊,因为我没有试过,真的很对不起,我学了C只有半个学期.......

ak_2005 · 2005-07-11

设断点（Ctrl+F8），单步执行（F7），查看联机帮助（Help->Index）...

linuxcici · 2005-07-15

ak_2005大侠我发了e-mail给你了,请看看.小弟现在能上网真的很不容易了,求你帮个忙
